The Flux-Five combines the liquid, sustaining, Boogie & Mark series lead tones of the original Flux-Drive pedal with the added shaping power of MESA's renowned Five Band Graphic EQ. The Flux-Five also features a foot switchable HI & LO Mode where LO represents the original Flux-Drive circuit and HI offers even MORE juicy, tasteful gain for anything from single note solos, rhythm work and all the way up to rock and heavy sounds and beyond.
This sample is a great example of the smooth, warm gain available from the Flux-Five in LO mode for tight & tasty rhythm work while still being warm and fat for single note solos. Add the EQ for a little extra Dumble-esque cut to your single notes. From there, the HI Mode is featured for a more searing and sustaining lead tone that adds girth and rich harmonic layering to your single notes while still remaining clear for chords and rhythmic playing.
